I expect the norm to be "no culture war" and "no politics" but there to be some flexibility. I don't want to end up with a LW where, say, this SSC post would be banned, and banning discussions of the rationality community that might get uncomfortable seems bad, and so on, but also I don't want to end up with a LW that puts other epistemic standards in front of rationality ones. (One policy we joked about was "no politics, unless you're Scott," and something like allowing people to put it on their personal page but basically never promoting it accomplishes roughly the same thing.)

Sorry, this might not be clear from the comment, but as a prospective writer I was primarily thinking about the comments on my posts. Even if I avoid culture war stuff in my posts, the comment section might go off on a tangent. (This is particularly a concern for me because of course my social-justice writing is the most well-known, so people might be primed to bring it up.) On my own blog, I tend to ban people who make me feel scared and defensive; if I don't have this capability and people insist on talking about culture-war stuff in the comments of my posts anyway, being on LW 2.0 will probably be unpleasant and aversive enough that I won't want to do it. Of course, I'm just one person and it doesn't make sense to set policy based on luring me in specific; however, I suspect this preference is common enough across political ideologies that having a way to accommodate it would attract more writers.

Got it; I expect the comments to have basically the same rules as the posts, and for you to be able to respond in some low-effort fashion to people derailing posts with culture war (by, say, just flagging a post and then the Sunshine Regiment doing something about it).
